The content is good for beginners, but it is annoying that "we" is always expressed as "us". The learners and the instructor are "us", and if there is an instructor and the instructor's staff, that group is "us" from the learners' perspective. I think that grammatical errors in oral speech are a huge risk in online lectures. I believe that you will be able to achieve better results if you improve them.

(I will add the content after completing the lecture)
I polluted the course review with Dae-heon feedback on parts unrelated to the lecture, but after completing the lecture, I found the entire lecture content very helpful to me. I took this course because I wanted to reorganize the basics and get rid of the amateurish(?) feeling of learning and using gRPC as an attribute out of necessity in the field, but it helped me understand the basic concepts and elements with easy examples better than I expected, and it introduced client concurrency processing and gRPC from an MSA perspective... I'm interested in gRPC but it's vague, or I've only dealt with RESTful APIs, so I didn't really feel like I could really use gRPC, so I think this was a great course to get started on, as it reduced my resistance.
